Folks i need some help with the abovementioned programmer. I built it on breadboard with a < 1m cable. the software ( pictest ) doesnt detect the board. First of all im running off a 9pin serial port and not a 25 pin as the schematic uses. could someone confirm that i have the correct pins on the DB9? Pin #3 TXD Pin #4 DTR Pin #5 GND Pin #7 RTS Pin #8 CTS What can i Check / Change to troubleshoot this programmer ? Also, im running it off a PIII 500 ( too fast maybe ?? ) Regards John -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
